Vichy is a city in the Allier department of Auvergne-Rhône-Alpes in central France, in the historic province of Bourbonnais.
It is a spa and resort town and in World War II was the seat of government of Vichy France from 1940 to 1944. The term Vichyste indicated collaboration with the Vichy regime, often carrying a pejorative connotation.
Today, the town's inhabitants are called Vichyssois. Up until the 18th century, they were more properly known as les Vichois, which stems from the Occitan name of the town, Vichèi. The writer Valery Larbaud uses the term Vicaldiens after the Ancient Roman Latin name for the community, aquae calidae.
